BACKGROUND OF THE INVENTION

While disposable absorbent garments offer a convenient way to managebedwetting, many enuretic families are not satisfied with these productsbecause they are viewed as “diaper-like” by the user who wants to wearconventional underwear. As such, many improvements have been made todisposable absorbent garments to make them more underwear-like. Forexample, gender specific graphics have been added and softer nonwovenmaterials have been utilized. However, many potential users still seek aproduct that looks and feels more like conventional underwear but isstill able to help manage bedwetting. Thus, there remains a need for apant that is underwear-like yet helps to contain urine insults.

The containment pant 10 defines alongitudinal direction 48 and a transverse direction 50 as illustratedin FIG. 1. The longitudinal direction 48 extends from the front waistregion 20 through the crotch region 28 and into the back waist region22. The transverse direction 50 is perpendicular to the longitudinaldirection 48. The chassis 12 includes an outer shell 36 and may furtherinclude waist elastic, leg elastic, or both. Referring again to FIG. 1,the chassis 12 is illustrated with a waist elastic 38 attached to theouter shell 36 and encircling the waist opening 16 and leg elastics 40attached to the outer shell 36 and encircling each of the leg openings18.

Another exemplary containment pant of the present invention isrepresentatively illustrated in FIGS. 6-8. Specifically, FIG. 6 shows aside perspective view of a containment pant 11 having a chassis 12 and asling 14 attached within the chassis 12. The chassis 12 defines a waistopening 16 and a pair of leg openings 18. The chassis 12 also defines afront waist region 20, a back waist region 22, and a crotch region 28.The crotch region 28 is located between the front waist region 20 andthe back waist region 22. The containment pant 11 of FIG. 6 is depictedin FIGS. 7 and 8 with the chassis 12 partially severed to betterillustrate internal elements. FIG. 7 representatively illustrates a sideperspective view with the chassis 12 partially severed to betterillustrate the positioning and construction of the sling 14 in the backof the containment pant 11. FIG. 8 representatively illustrates a sideperspective view with the chassis 12 partially severed to betterillustrate the construction and positioning of the sling 14 in the frontof the containment pant 11. The containment pant 11 also defines alongitudinal direction 48 and a transverse direction 50 as illustratedin FIG. 6. The chassis 12 includes an outer shell 37 and may furtherinclude a waist elastic 38 or leg elastics 40, or both. Referring againto FIG. 6, the chassis 12 is illustrated with a waist elastic 38attached to the outer shell 37 and encircling the waist opening 16 andleg elastics 40 attached to the outer shell 37 and encircling each ofthe leg openings 18.

In various embodiments, the outer shell may be made of a single piece ofmaterial or multiple pieces of material. In some embodiments, the outershell may be made of two or more pieces of material. For example, FIG. 4is a top plan view of the component pieces of the outer shell 36 ofFIGS. 1-3. The component pieces include a front component 21 and a backcomponent 23. In another example, FIG. 9 is a top plan view of thecomponent pieces of the outer shell 37 of FIGS. 6-8. The componentpieces include a front component 24 and a back component 31.

In various embodiments, the component pieces of the outer shell may bejoined together in any suitable manner. For example, the front component21 may be joined to the back component 23 at a crotch seam 29 asillustrated in FIG. 5. FIG. 5 is a top plan view of the component piecesof the outer shell 36 partially joined together. In another example, thefront component 24 may be joined to the back component 31 at a crotchseam 29 as illustrated in FIG. 10. FIG. 10 is a top plan view of thecomponent pieces of the outer shell 37 partially joined together.Additionally, one or both of the lateral side edges of the backcomponent may be joined to one or both of the lateral side edges of thefront component at one or more side seams to define a three-dimensionalgarment. Specifically, referring to FIG. 5, the lateral side edges 25 ofthe back component 23 may be joined with the lateral side edges 27 ofthe front component 21 at side seams 26 to define the leg openings 18and the waist opening 16 of the containment pant 10 as illustrated inFIG. 1. Similarly, the lateral side edges 25 of the back component 31 ofFIG. 10 may be joined with the lateral side edges 27 of the frontcomponent 24 at side seams 26 to define the leg openings 18 and thewaist opening 16 of the containment pant 11 as illustrated in FIG. 6.

In various embodiments, the side seams and/or the crotch seams may beformed using any suitable means such as ultrasonic bonding, thermalbonding, adhesive bonding, pressure bonding, sewing, and the like andcombinations thereof. In some embodiments, the side seams and/or thecrotch seam may be formed by sewing the component pieces of the outershell using thread and any suitable stitch pattern or combination ofpatterns. In some embodiments, the side seams and/or crotch seams may beformed using a flatlock stitch.

In some embodiments, the present invention provides a first outer shellhaving a first overall shape and a second outer shell having a secondoverall shape that is different than the first overall shape. In someembodiments, the first outer shell shape may be adapted to the anatomyof a male wearer. In some embodiments, the second outer shell shape maybe adapted to the anatomy of a female wearer. Customizing the firstouter shell and/or the second outer shell is believed to be beneficialto allow for differences between the genders in anatomy, body shape, andundergarment style preferences. For example, the outer shell 36illustrated in FIG. 1 has a shape and style adapted for males. Incomparison, the outer shell 37 illustrated in FIG. 6 has a shape andstyle adapted for females. In some embodiments, the front components 21may include protrusions 98 for partially defining the leg openings asillustrated in FIGS. 4 and 5. Additionally, the back component 23 mayalso include protrusions 98 for partially defining the leg openings asillustrated in FIGS. 4 and 5. In various embodiments, the frontcomponent may have an area that is similar in size to the area of theback component as illustrated in FIGS. 9 and 10. In other embodiments,the front component may have an area that is significantly smaller thanthe area of the back component as illustrated in FIGS. 4 and 5.

In various embodiments, the waist elastic may encircle at least 50, 60,70, 80, or 90 percent of the respective waist opening. In someembodiments, the waist elastic 38 may encircle 100% of the waist opening16 as representatively illustrated in FIGS. 1 and 6. In variousembodiments, the leg elastic may encircle at least 50, 60, 70, 80, or 90percent of either or both leg openings. In some embodiments, the legelastic 40 may encircle 100% of both leg openings 18 as representativelyillustrated in FIGS. 1 and 6.

In various embodiments, the waist elastic and/or the leg elastic may bein complete facing relationship with the outer shell (Not shown). Insome embodiments, the waist elastic and/or the leg elastic may bepartially or completely encased within the outer shell (Not shown). Inother embodiments, the waist elastic and/or the leg elastic may becantilevered relative to the outer shell. As used herein, the term“cantilevered” refers to a waist elastic and/or leg elastic that hasless than 100% facing relationship with the outer shell and extendsbeyond an outer edge of the outer shell. For example, referring again toFIGS. 2 and 7, the waist elastics 38 are cantilevered as they extendbeyond the outer edge 46 of the respective outer shells 36 and 37.Likewise, the leg elastics 40 are also cantilevered as they extendbeyond the outer edge 46 of the respective outer shells 36 and 37.

In various embodiments, the waist elastic and/or leg elastic may bejoined with the outer shell using any suitable means such as ultrasonicbonding, thermal bonding, adhesive bonding, pressure bonding, sewing,and the like and combinations thereof. In some embodiments, the waistelastic and/or leg elastic may be sewed to the outer shell using threadand any suitable stitch pattern or combination of patterns. For example,FIGS. 1-3 and FIGS. 6-8 representatively illustrate the waist elastic 38joined with the respective outer shells 36 and 37 at a sewn waistelastic seam 39 and the leg elastics 40 joined with the respective outershells 36 and 37 at sewn leg elastic seams 41. In some embodiments, thewaist elastic and/or leg elastic may be sewed to the outer shell using acover stitch.

Inside the chassis 12 is the sling 14, which includes a fluid-imperviousbase sheet 30 and at least one containment flap 32 joined with the basesheet 30 to create a fluid-impervious pouch 34. The fluid-imperviouspouch 34 is adapted to house a removable absorbent insert and containfluid until it can be taken into the absorbent insert. Thefluid-impervious pouch 34 is drapeable and is designed to conform andgasket against the body of the wearer.

In some embodiments, the sling 14 may further include a firsttransition, a second transition, or both. The first transition and thesecond transition are believed to be beneficial in that they allow thefluid-impervious pouch to be joined within the chassis withoutsignificantly reducing the extension and retraction properties of theouter shell and/or the waist elastic. Additionally, the first transitionand the second transition are believed to be beneficial by allowing thefluid-impervious pouch to move from front to back within the chassis.This freedom of movement is believed to allow the fluid-impervious pouchto adjust after donning the containment pant and during wear.

Referring again to FIGS. 2 and 7, the sling 14 is illustrated with asecond transition 42 joined with the back waist region 22 of thecontainment pant. Likewise, in FIGS. 3 and 8, the sling 14 isillustrated with a first transition 44 joined with the front waistregion 20 of the containment pant. Alternatively, in any of theembodiments described herein, the second transition may be joined withthe front waist region and the first transition may be joined with theback waist region. In various embodiments, the first transition, thesecond transition, or both, may be one or more discrete pieces ofmaterial joined between the pouch and the chassis. In other embodiments,the first transition, the second transition, or both, may be integralwith the pouch or may be integral with the shell or any suitable portionof the chassis.

For example, FIG. 3 illustrates the first transition 44 as integral withthe shell components and FIG. 2 illustrates the second transition 42 asa discrete piece of material. In this embodiment, the first transition44 is constructed from multiple portions of the shell 36. As seen inFIGS. 4 and 5, the first transition 44 is constructed from a first part44A, a second part 44B, and a third part 44C. The first part 44A and thesecond part 44B are integral with the back component 23 of the shellwhereas the third part 44C is integral with the front component 21 ofthe shell. When the shell is constructed, the first part 44A and thesecond part 44B are joined with the third part 44C as illustrated by thearrows of FIG. 5. The fully constructed first transition 44 is thenfolded along the fold lines 33 of FIG. 5 to define the first transition44 as illustrated in FIG. 3.

In another example, FIG. 8 also illustrates the first transition 44 asintegral with the shell components and FIG. 7 illustrates the secondtransition 42 as a discrete piece of material. In this embodiment, thefirst transition 44 is constructed from a single portion of the shell37. As seen in FIGS. 9 and 10, the first transition 44 is constructedfrom a portion of the front component 24 of the shell. When the shell isconstructed, the first transition 44 is then folded along fold line 33of FIG. 10 to define the first transition 44 as illustrated in FIG. 8.

In various embodiments, a sling and a fluid-impervious pouch may beconstructed in any suitable manner. For example, an exemplary sling andfluid-impervious pouch may include a containment flap, a base sheet, afirst transition, and a second transition. Referring now to FIG. 11, atop plan view of the component parts of an exemplary pouch and sling arerepresentatively illustrated. A fully constructed pouch 68 made from thecomponent parts of FIG. 11 is representatively illustrated in FIG. 12. Afully constructed sling made from the component parts of FIG. 11 isrepresentatively illustrated in FIG. 13. A cross sectional view of thesling 52 of FIG. 13 taken along the line A-A is representativelyillustrated in FIG. 14.

Referring now to FIG. 11, the component parts include a containment flap54, a base sheet 56, a first transition 58, and a second transition 60.The containment flap 54 defines a proximal portion 62 and a distalportion 64. The proximal portion 62 of the containment flap 54 is joinedwith the base sheet 56 to create a containment flap seal 66 and define afluid-impervious pouch 68 as illustrated in FIG. 12. In someembodiments, the containment flaps may further include one or moreelastics. For example, as illustrated in FIG. 14, the distal portion 64of the containment flap 54 further includes a containment flap elastic70.

In various embodiments, the fluid-impervious pouch 68 of FIG. 12 may beincorporated into any suitable sling and/or chassis using integratedtransitions, discrete transitions, or combinations thereof. In variousembodiments, the fluid-impervious pouch 68 of FIG. 12 may beincorporated into any suitable sling and/or chassis using only atransition joined with the front waist region, only a transition joinedwith the back waist region, or neither. In FIG. 13 the fluid-imperviouspouch 68 of FIG. 12 is joined with the first transition 58 and thesecond transition 60 to define the sling 52. Referring now to FIGS.11-13, the first transition 58 defines a first edge 82 and a second edge84. Likewise, the second transition 60 defines a first edge 90 and asecond edge 92. The base sheet 56 defines a first edge 86 and a secondedge 88. The first edge 86 of the base sheet 56 is joined with thesecond edge 84 of the first transition 58 to define a first junction 72.Likewise, the second edge 88 of the base sheet 56 is joined with thefirst edge 90 of the second transition 60 to define a second junction74.

In various embodiments, the sling 52 of FIG. 13 can be joined with anysuitable chassis to form a containment pant. In various embodiments, thesling 52 may be joined with a chassis such that the first transition islocated in either the front waist region or the back waist region of thechassis and the second transition is located in the opposite region ofthe chassis. For example, referring now to FIGS. 15 and 16, an exemplarycontainment pant 53 having a chassis 51 and the sling 52 of FIG. 13 isrepresentatively illustrated. FIG. 15 is a side perspective view of thecontainment pant 53 with the chassis 51 partially severed to illustratethe attachment of the sling 52 in the back waist region 22.Specifically, the second transition 60 is joined with the back waistregion 22 of the chassis 51 at a back sling seam 43. FIG. 16 is a sideperspective view of the containment pant 53 with the chassis 51partially severed to illustrate the attachment of the sling 52 in thefront waist region 20. Specifically, the first transition 58 is joinedwith the front waist region 20 of the chassis 51 at a front sling seam45.

Likewise, the portion of the base sheet106 proximate the second fold line 146 is joined with the first edge 140of the second transition 110 to define a second junction 124 asillustrated in FIG. 19.

In various embodiments, the side containment flaps may have a curve cutor a straight cut. For example, the first side containment flap 104 andthe second side containment flap 105 of FIG. 17 are illustrated ashaving a curve cut. Similarly, the first side containment flap 330 andthe second side containment flap 332 of FIG. 28 also illustrate a curvecut. In contrast, the containment flap 54 in FIG. 11 is exemplary of astraight cut flap. While not wishing to be bound by theory, it isbelieved that the curve cut containment flaps facilitate closeralignment with the natural curvature of the wearer's body. As such, itis believed that a more comfortable and better fit can be achieved.

The proximal portions 112 of each of the side containment flaps 104 and105 are joined with the base sheet 106 and/or the first end containmentflap 148 and/or the second end containment flap 150 to form containmentflap seals 116 and to partially define a fluid-impervious pouch 118 asillustrated in FIG. 18. In various embodiments, one or both end flapsmay be positioned between one or both of the containment flaps and thebase sheet. In other embodiments, one or both of the containment flapsmay be positioned between one or both of the end flaps and the basesheet. For example, in some embodiments, both end flaps may bepositioned between both containment flaps and the base sheet asillustrated in FIG. 18. In other embodiments (not illustrated), bothcontainment flaps may be positioned between both end flaps and the basesheet.

In various embodiments, the end flap may also include an end flap seal117. The end flap seal 117 may join the first side containment flap 104and/or the second side containment flap 105 to the first end containmentflap 148 and/or the second end containment flap 150 and/or the basesheet 106 to define the fluid impervious pouch 118 in conjunction withthe containment flap seals 116. In various embodiments, the overlapregion 119 between the side containment flaps 104 and 105 and the endcontainment flaps 148 and 150 may be joined via any suitable manner todefine a completely fluid impervious pouch 118. For example, in someembodiments, the side containment flaps 104 and 105 may be joined withthe end containment flaps 148 and 150 in the overlap regions 119 byadhesive bonding, stitching, ultrasonic bonding, thermal bonding,pressure bonding, and the like, and combinations thereof. For example,the distal portions 114 of the first side containment flap 104 and thesecond side containment flap 105 may be completely joined with the endcontainment flaps 148 and 150 in the overlap regions 119 to ensure thatthe pouch 118 is completely fluid-impervious.

In various embodiments, any or all of the side containment flaps and/orthe end containment flaps may further include one or more elastics. Forexample, the distal portions 114 of the side containment flaps 104 and105 may further include containment flap elastic 120 as illustrated inFIG. 20.

In some embodiments, the first end containment flap and/or the secondend containment flap may further include an insert stop that limits thedepth to which an absorbent insert can be inserted. For example, thesecond end containment flap 150 of FIG. 18 is illustrated with an insertstop 147. In this embodiment, the insert stop 147 is illustrated as anultrasonic bond between the second end containment flap 150 and the basesheet 106. In various embodiments, the insert stops may be any suitablelength or width and may be positioned at any suitable depth within thefirst end containment pocket and/or the second end containment pocket.In some embodiments, the insert stop may extend from one containmentflap seal to the other containment flap seal (not illustrated). In otherembodiments, the insert stop 147 may terminate short of one or bothcontainment flap seals 116 and thereby allow fluid within the second endcontainment pocket 150 to flow around the insert stop 147 and into areservoir 145. In effect, this configuration provides greater volume forcontaining insults while still providing a suitably sized pocket forretention of the absorbent insert.

In various embodiments, the fluid-impervious pouch 118 of FIG. 18 may beincorporated into any suitable sling and/or chassis using integratedtransitions, discrete transitions, or combinations thereof. In variousembodiments, the fluid-impervious pouch 118 of FIG. 18 may beincorporated into any suitable sling and/or chassis using only atransition joined with the front waist region, only a transition joinedwith the back waist region, or neither. In the illustrated embodiment,the fluid-impervious pouch 118 of FIG. 18 is joined with the firsttransition 108 and the second transition 110 to define the sling 102 ofFIG. 19.

In various embodiments, the sling 102 of FIG. 19 can be joined with anysuitable chassis to form a containment pant. In various embodiments, thesling 102 may be joined with a chassis such that the first transition islocated in either the front waist region or the back waist region of thechassis and the second transition is located in the opposite region ofthe chassis. For example, referring now to FIGS. 21 and 22, an exemplarycontainment pant 103 having a chassis 101 and the sling 102 isrepresentatively illustrated. FIG. 21 is a side perspective view of thecontainment pant 103 with the chassis 101 partially severed toillustrate the attachment of the sling 102 in the back waist region 22.Specifically, the second transition 110 is joined with the back waistregion 22 of the chassis 101 at a back sling seam 43. FIG. 22 is a sideperspective view of the containment pant 103 with the chassis 101partially severed to illustrate the attachment of the sling 102 in thefront waist region 20. Specifically, the first transition 108 is joinedwith the front waist region 20 of the chassis 101 at a front sling seam45.

In another embodiment, a sling and a fluid-impervious pouch may beconstructed with a base sheet, a first transition, and a secondtransition. For example, referring now to FIG. 23, a top plan view ofthe component parts of another exemplary pouch and sling arerepresentatively illustrated. A fully constructed pouch 206 made fromsome of the component parts of FIG. 23 is representatively illustratedin FIG. 24. A fully constructed sling 152 made from the component partsof FIG. 23 is representatively illustrated in FIG. 25. The componentparts include a base sheet 154, a first transition 156, and a secondtransition 158. The base sheet 154 includes a first arm 160, a secondarm 162, a third arm 164, and a fourth arm 166. The base sheet 154defines an absorbent facing surface 168 and a chassis facing surface170.

Referring now to FIGS. 23 and 24, the first arm 160 and the second arm162 are folded towards the absorbent facing surface 168 of the basesheet 154 in the direction indicated by arrows 172. A distal portion 174of the first arm 160 is joined with a distal portion 176 of the secondarm 162 to define a first bridging seam 178. Likewise, the third arm 164and the fourth arm 166 are folded towards the absorbent facing surface168 of the base sheet 154 in the direction indicated by arrows 180. Adistal portion 182 of the third arm 164 is joined with a distal portion184 of the fourth arm 166 to define a second bridging seam 186. An innerportion 188 of the first arm 160 is joined with a first portion 190 ofthe base sheet 154 to define a portion of a first containment seam 194.Likewise, an inner portion 192 of the second arm 162 is joined with thefirst portion 190 of the base sheet 154 to define the remainder of thefirst containment seam 194. An inner portion 196 of the third arm 164 isjoined with a second portion 198 of the base sheet 154 to define aportion of a second containment seam 200. Likewise, an inner portion 202of the fourth arm 166 is joined with the second portion 198 of the basesheet 154 to define the remainder of the second containment seam 200.

By folding the first arm 160 and the second arm 162 in the directionindicated by arrows 172, the lateral side edges 204 of the base sheet154 tend to bend towards the absorbent facing surface 168 of the basesheet 154. Similarly, by folding the third arm 164 and the fourth arm166 in the direction indicated by arrows 180, the lateral side edges 204of the base sheet 154 tend to bend in the same manner to definecontainment flap 205. As such, the base sheet 154 is cupped to define afluid-impervious pouch 206 having containment flap 205 as illustrated inFIG. 24.

In various embodiments, the fluid-impervious pouch 206 of FIG. 24 may beincorporated into any suitable sling and/or chassis using integratedtransitions, discrete transitions, or combinations thereof. In variousembodiments, the fluid-impervious pouch 206 of FIG. 24 may beincorporated into any suitable sling and/or chassis using only atransition joined with the front waist region, only a transition joinedwith the back waist region, or neither. In the illustrated embodiment,the fluid-impervious pouch 206 is joined with the first transition 156and the second transition 158 to define the sling 152 as illustrated inFIG. 25. In this embodiment, the first transition 156 defines a firstedge 210 and a second edge 212 and the second transition 158 defines afirst edge 214 and a second edge 216. The first portion 190 of the basesheet 154 is joined with the second edge 212 of the first transition 156to define a first junction 218. Likewise, the second portion 198 of thebase sheet 154 is joined with the first edge 214 of the secondtransition 158 to define a second junction 220. In some embodiments, thefluid-impervious pouch 206 may define a distal edge and may include oneor more elastics. For example, as illustrated in FIG. 24, the distaledge 208 of the pouch 206 further includes a pouch elastic 209.

In various embodiments, the sling 152 of FIG. 25 can be joined with anysuitable chassis to form a containment pant. In various embodiments, thesling 152 may be joined with a chassis such that the first transition islocated in either the front waist region or the back waist region of thechassis and the second transition is located in the opposite region ofthe chassis. For example, referring now to FIGS. 26 and 27, an exemplarycontainment pant 153 having a chassis 151 and the sling 152 isrepresentatively illustrated. FIG. 26 is a side perspective view of thecontainment pant 153 with the chassis 151 partially severed toillustrate the attachment of the sling 152 in the back waist region 22.Specifically, the second transition 158 is joined with the back waistregion 22 of the chassis 151 at a back sling seam 43. FIG. 27 is a sideperspective view of the containment pant 153 with the chassis 151partially severed to illustrate the attachment of the sling 152 in thefront waist region 20. Specifically, the first transition 156 is joinedwith the front waist region 20 of the chassis 151 at a front sling seam45.

In another embodiment, a fluid-impervious pouch may be constructed witha first containment flap, a second containment flap, a third containmentflap, a fourth containment flap, and a base sheet. For example,referring now to FIG. 28, a top plan view of the component parts ofanother exemplary pouch are representatively illustrated. A fullyconstructed pouch 346 made from the component parts of FIG. 28 isrepresentatively illustrated in FIG. 29.

The component parts include a first side containment flap 330, a secondside containment flap 332, a first end containment flap 334, a secondend containment flap 336, and a base sheet 338. The containment flaps330, 332, 334, and 336 each define a proximal portion 340 and a distalportion 342.

The proximal portions 340 of each of the containment flaps 330, 332,334, and 336 are joined with the base sheet 338 to form containment flapseals 344 and to define a fluid-impervious pouch 346 as illustrated inFIG. 29. In various embodiments, one or both end flaps may be positionedbetween one or both of the containment flaps and the base sheet. Inother embodiments, one or both of the containment flaps may bepositioned between one or both of the end flaps and the base sheet. Forexample, in some embodiments, both end flaps may be positioned betweenboth containment flaps and the base sheet as illustrated in FIG. 29. Inother embodiments (not illustrated), both containment flaps may bepositioned between both end flaps and the base sheet.

In various embodiments, the overlap region 349 between the sidecontainment flaps 330 and 332 and the end containment flaps 334 and 336may be joined together via any suitable manner to at least partiallydefine the completely fluid impervious pouch 346. For example, in someembodiments, the side containment flaps 330 and 332 may be joined withthe end containment flaps 334 and 336 in the overlap regions 349 byadhesive bonding, stitching, ultrasonic bonding, thermal bonding,pressure bonding, and the like, and combinations thereof. For example,the distal portions 342 of the first side containment flap 330 and thesecond side containment flap 332 may be completely joined with the endcontainment flaps 334 and 336 in the overlap regions 349 to ensure thatthe pouch 346 is completely fluid-impervious. In other embodiments, thedistal portions of the first end containment flap and the second endcontainment flap may be completely joined with the side containmentflaps in the overlap region to ensure the pouch is completelyfluid-impervious (not shown).

In various embodiments, one or more of the containment flaps may furtherinclude one or more elastics. For example, the distal portions 342 ofthe containment flaps 330, 332, 334, and 336 may further includecontainment flap elastic 345. In various embodiments, thefluid-impervious pouch 346 of FIG. 29 may be incorporated into anysuitable sling and/or chassis using integrated transitions, discretetransitions, or combinations thereof. In various embodiments, thefluid-impervious pouch 346 of FIG. 29 may be incorporated into anysuitable sling and/or chassis using only a transition joined with thefront waist region, only a transition joined with the back waist region,or neither.

Referring now to FIGS. 30 and 31, the fluid-impervious pouch 346 of FIG.29 is joined with a first transition 350 and a second transition 352 todefine a sling 348 suspended within an exemplary containment pant 354.In various embodiments, the pouch 346 can be joined within any suitablechassis to form a containment pant. In various embodiments, the pouch346 may be joined with a chassis via a first transition that is locatedin either the front waist region or the back waist region of the chassisand via a second transition that is located in the opposite region ofthe chassis. FIG. 30 is a side perspective view of the containment pant354 with the chassis 353 partially severed to illustrate the attachmentof the pouch 346 in the back waist region 22 via the second transition352. The second transition 352 is joined with the back waist region 22of the chassis 353 at a back sling seam 43. FIG. 31 is a sideperspective view of the containment pant 354 with the chassis 353partially severed to illustrate the attachment of the pouch 346 in thefront waist region 20 via the first transition 350. In the illustratedembodiment, the first transition 350 is a discrete piece of materialjoined with the front waist region 20 of the chassis 353 while thesecond transition 352 is a discrete piece of material joined with theback waist region 22 of the chassis 353.

In general, any of the containment flaps described herein, may furtherinclude one or more containment flap elastics. The containment flapelastics may be joined with the containment flaps in any suitableconfiguration using any suitable attachment means. For example, in someembodiments, the containment flap elastics may be joined with thecontainment flaps using mechanical encasement, adhesive bonding, thermalbonding, ultrasonic bonding, pressure bonding, sewing, or the like, orcombinations thereof.

In some embodiments, the containment flap elastic may be encased, atleast partially, within a channel formed by folding a portion of thecontainment flap. For example, FIG. 14 representatively illustrates across sectional view of the sling 52 of FIG. 13 taken along the lineA-A. In this embodiment, the proximal portion 62 of the containment flap54 is bonded to the base sheet 56 to form containment flap seals 66. Thedistal portion 64 of the containment flap 54 is folded over upon itselfand bonded to itself to form a channel 71. The containment flap elastic70 is encased within the channel 71 and may be partially attached to thecontainment flap 54. In other embodiments, the containment flap elasticmay be disposed within the channel but not attached to the containmentflap.

In some embodiments, the containment flap elastic may be folded over thedistal edge of the containment flap. For example, FIG. 20representatively illustrates a cross sectional view of the sling 102 ofFIG. 19 taken along the line B-B. In this embodiment the proximalportion 112 of the containment flaps 104 and 105 are bonded to the basesheet 106 to form containment seals 116. The containment flap elastic120 is folded over the distal edge 121 of the first side containmentflap 104 and the second side containment flap 105. The containment flapelastics 120 may be joined with the side containment flaps 104 and 105by any suitable method, such as sewing.

In various embodiments, the attachment of the containment flap elasticto the containment flap can be adjusted to vary the tension in thecontainment flap. For example, in some embodiments, the containment flapelastic may be applied at a uniform tension and select portions can bedeadened to provide a containment flap elastic having variable tensionalong the length of the containment flap. In some embodiments, thecontainment flap elastic may be applied at variable tension to provide acontainment flap elastic having variable tension along the length of thecontainment flap.

In various embodiments, the containment flaps may be integral with thebase sheet. For example, the containment flap 205 illustrated in FIG. 24is integral with the base sheet 154. In other embodiments, thecontainment flaps may be discrete pieces of material that are joinedwith the base sheet using any suitable method to at least partiallydefine the pouch. For example, the containment flap 54 illustrated inFIG. 12 is discrete from and joined with the base sheet 56 at thecontainment flap seal 66. In some embodiments, one or more containmentflaps may be integral with the base sheet and one or more of containmentflaps may be discrete pieces. For example, FIG. 18 illustrates the firstend containment flap 148 and the second end containment flap 150 beingintegral with the base sheet 106 while the first side containment flap104 and second side containment flap 105 are discrete from and joinedwith the base sheet 106 at the containment flap seals 116.

In various embodiments, the discrete containment flaps may be joinedwith the base sheet in any suitable manner. For example, the containmentflaps may be sewed to the base sheet, heat bonded, adhesively bonded,ultrasonically bonded, seam taped, or the like, or combinations thereof.In embodiments wherein the pouch is fluid-impervious, the discretecontainment flaps are joined to the base sheet to provide afluid-impervious seal. The fluid-impervious seal is believed to preventleakage from the pouch until the absorbent insert is able to intake thefluid.

In some embodiments, the fluid-impervious seal is created, at least inpart, using ultrasonic bonding. Ultrasonic bonding fuses the base sheetmaterial to the containment flap material. The ultrasonic bonding mayutilize any suitable bonding pattern to regulate the bond strength ofthe seal. For example, the ultrasonic bond pattern may be one or morerows of “dash” bonds. For example, in some embodiments, the bond patternmay include three rows of offset dash bonds like illustrated in FIG. 13.In other embodiments, the ultrasonic bond pattern may include one ormore continuous “wave” bond patterns. For example, in some embodiments,the bond pattern may include a single continuous wave bond pattern asillustrated in FIG. 18. In other embodiments, the ultrasonic bondpattern may include one or more rows of “dot” bonds. For example, insome embodiments, the bond pattern may include two rows of offset dotbonds as illustrated in FIG. 24. The ultrasonic bonding may beaccomplished using a standard ultrasonic horn and anvil. In someembodiments, the ultrasonic bonds may be created using a sonic sewingmachine. A suitable machine is available from Sonobond and has modelnumber LM920.

The use of ultrasonic bonding is believed to be beneficial in someembodiments over sewing because no holes are created in the containmentflap and thus the integrity of the pouch is preserved. Likewise, the useof ultrasonic bonding is believed to be beneficial in some embodimentsover seam tape because the base sheet and/or containment flaps couldmelt at the application temperature of typical seam tape. In someembodiments, the base sheet is made of a polyurethane and polyesterlaminate and the containment flaps are made of a polyurethane andpolyester laminate. In these embodiments, the base sheet and thecontainment flap can be constructed with ultrasonic bonding to create astrong seal without burning through either the base sheet or thecontainment flap.

The flap seals collectively define a flap seal perimeter. The portion ofthe base sheet circumscribed by the flap seal perimeter constitutes thepouch floor. For example, referring now to FIG. 29, the containmentflaps 330, 332, 334, and 336 are joined to the base sheet 338 at theflap seals 344 and define a flap seal perimeter 356. The location on thebase sheet 338 where the flap seal perimeter 356 will be formed is shownwith a dashed line on FIG. 28 for purposes of illustration. In general,the portion of the base sheet 338 circumscribed by the flap sealperimeter 356 constitutes the pouch floor 358. The pouch floor 358defines a pouch floor length 360, a pouch floor width 362, and a pouchfloor area 364.

In any of the embodiments disclosed herein, one or more of thecontainment flaps may further include an absorbent insert stop. Theabsorbent insert stop may be any suitable physical barrier that limitsthe depth of insertion of the absorbent insert into one or more of thecontainment flaps. In various embodiments the absorbent insert stop maybe a mechanical bond between the containment flap and the base sheet.The mechanical bond may be an ultrasonic bond, a thermal bond, astitched bond, a pressure bond, an adhesive bond, or the like, or acombination thereof. For example, referring now to FIG. 29, the secondend containment flap 336 is illustrated with an absorbent insert stop351. In this embodiment, the absorbent insert stop 351 is illustrated asan ultrasonic bond that limits the depth of insertion of the absorbentinsert into the second end containment flap 336. In another example, thesecond end containment flap 150 of FIG. 18 is illustrated with an insertstop 147 that is an ultrasonic bond between the second end containmentflap 150 and the base sheet 106.

In embodiments having one or more absorbent insert stops, the pouchfloor length and the pouch floor area are defined in part by thecontainment flap seal and in part by the absorbent insert stop. Forexample, referring again to FIG. 28, the location on the base sheet 338where the absorbent insert stop 351 will be formed is shown with adashed line for purposes of illustration. In embodiments with theabsorbent insert stop 351, the pouch floor 358 defines a pouch floorlength 360 and a pouch floor area 365. In these embodiments, the pouchfloor length 361 is defined by the end portion 355 of the containmentflap seal 344 and the absorbent insert stop 351. Likewise, the pouchfloor area 364 is defined by the absorbent insert stop 351 and the sideportions 357 of the containment flap seal 344 up to the points where theabsorbent insert stop 351, if extended, would intersect the containmentflap seal 344.

In embodiments that include one or more absorbent insert stops, thepouch floor may also define a reservoir portion that extends between theabsorbent insert stop and the containment flap seal under a containmentflap. For example, referring again to FIGS. 28 and 29, the pouch floor358 defines a reservoir portion 359 that extends from the absorbentinsert stop 351 to the end portion 363 of the containment flap seal 344.In another example, referring now to FIG. 18, the pouch 118 includes areservoir portion 145 that extends from the absorbent insert stop 147 tothe end flap seal 117. As discussed previously, the insert stops may beany suitable length or width and may be positioned at any suitable depthwithin the first end containment pocket and/or the second endcontainment pocket. In some embodiments, the absorbent insert stops mayterminate short of one or both containment flap seals and thereby allowfluid within the containment pocket to flow around the absorbent insertstop and into the reservoir portion. In various embodiments, thereservoir portion may have a length of about 50 to 70 mm or about 60 mm.

The pouch floor 358 also defines a first end section 366, a second endsection 367, and a central section 368 in the longitudinal direction 48.The central section 368 extends between the first end section 366 andthe second end section 367. The first end section 366 defines a firstend section width 369 and a first end section length 370. The second endsection 367 defines a second end section width 371 and a second endsection length 372. The central section 368 defines a central sectionwidth 373 and a central section length 374. The first end section length370 plus the second end section length 372 plus the central sectionlength 374 equals the pouch floor length. The widths of the varioussections are measured in the transverse direction 50 and the lengths ofthe various sections are measured in the longitudinal direction 48. Thepouch floor dimensions are measured on an assembled pouch by tracingaround the inner edge of the flap seal perimeter with a pen, cutting thecontainment flaps and elastic from the pouch, and laying the pouch floorflat. If no flap seal is present, the pouch floor is defined relative tothe distal edge of the containment flap. Specifically, in theseembodiments, the pouch floor is defined by the position 30 mm from thedistal edge of the containment flap.

In an embodiment adapted for children weighing 60 to 120 pounds, whichmay be characterized as size large and/or extra large, the pouch floorlength may be 380 to 500 mm, or 410 to 470 mm, or about 440 mm. In anembodiment adapted for children weighing 38 to 65 pounds, which may becharacterized as small and/or medium, the pouch floor length may be 350to 450 mm, 375 to 425 mm, or about 400 mm. In some of these embodiments,the pouch floor may also include a reservoir having a length of 50 to 70mm or about 60 mm.

In various embodiments, the first end section length may equal thecentral section length which may equal the second end section length. Inother embodiments, the first end section length may equal the second endsection length and the central section length may be different. Forexample, the first end section length may be about 35% the pouch floorlength, the second end section length may be about 35% the pouch floorlength, and the central section length may be about 30% the pouch floorlength. In another example, the first end section length may be about30% the pouch floor length, the second end section length may be about30% the pouch floor length, and the central section length may be about40% the pouch floor length.

In various embodiments, the pouch floor may have a width that varies atdifferent points along the longitudinal direction. For example, asillustrated in FIG. 28, the pouch floor 358 has a variable width atdifferent points along the longitudinal direction. In this embodiment,the first end section 366 and the second end section 368 have a maximumwidth that is greater than the maximum width of the central section 367.For example, the first end section and the second end section may have amaximum width of about 145 to 195 mm, about 160 to 190 mm or about 180mm. In these embodiments, the central section may have a maximum widthof about 60 to 100 mm, about 70 to 90 mm, or about 82 mm.

In various embodiments, the first end section, the second end section,and/or the central section may have a variable width at different pointsalong the longitudinal direction or may have a consistent width atdifferent points along the longitudinal direction. In some embodiments,the first end section and the second end section may have variable widthat different points along the longitudinal direction and the centralsection may have a consistent width at different points along thelongitudinal direction as illustrated in FIG. 28. In some embodiments,the first end section and the second end section may have a width thatvaries from 180 mm at the maximum to 82 mm at the minimum. In theseembodiments, the central section may have a consistent width of about 82mm.

In some embodiments, the pouch floor defines a first reference width 376measured at ⅛ the pouch floor length, a second reference width 377measured at ½ the pouch floor length, and a third reference width 378measured at ⅞ the pouch floor length. In some embodiments, the firstreference width 376 may be equal to the third reference width 378 andthe second reference width 377 may be less than the first and thirdreference widths 376 and 378. In some embodiments, the second referencewidth 377 may be less than 50%, 60%, 70%, or 80% the first referencewidth 376 and/or the third reference width 378. In some embodiments, thesecond reference width 377 may be about 48% the first reference width376 and the third reference width 378.

In various embodiments, the pouch floor area may be any suitable value.For example, in embodiments adapted for children weighing 60 to 120pounds, the pouch floor area may be about 55,000 mm². In embodimentsadapted for children weighing 38 to 65 pounds, the pouch floor area maybe about 47,700 mm².

In various embodiments, the pouch floor may define any suitable shape.For example, the pouch floor may have a symmetric shape about thetransverse centerline or may have an asymmetric shape about thetransverse centerline. In various embodiments, the pouch floor may havea dog-bone-shape, hourglass-shape, T-shape, rectangular shape, or thelike.

In various embodiments, the pouches of the present invention may bejoined with one or more transitions in any suitable manner. For example,the pouches may be joined with the transitions by sewing, ultrasonicbonding, thermal bonding, adhesive bonding, seam taping, and the like,and combinations thereof. In some embodiments, the transitions may bejoined with the pouches by sewing, using any suitable stitch orcombination of stitches. For example, in some embodiments, thetransitions may be attached to the pouches using a single needle stitchfollowed by a top stitch.

In some embodiments, the pouches may be constructed such that extramaterial is available for attaching the transitions without breachingthe fluid-impervious integrity of the pouch. For example, in someembodiments, the containment flap may be joined to the base sheet at thecontainment flap seal. The containment flap seal may be positioned suchthat a portion of the containment flap material and/or the base sheetmaterial is available for attaching to the first and/or secondtransition while maintaining the integrity of the fluid-imperviouspouch.

In some embodiments, the sling is minimally attached to the chassis tomaximize the fit and natural movement of the chassis. In someembodiments, the sling is attached to the chassis via the firsttransition and/or the second transition. In various embodiments, thefirst transition may be joined with the front waist region at the frontsling seam and the second transition may be joined with the back waistregion at the back sling seam. In other embodiments, the firsttransition may be joined with the back waist region at the back slingseam and the second transition may be joined with the front waist regionat the front sling seam. The first transition and/or the secondtransition may be joined to any suitable portion of the front waistregion and/or the back waist region. For example, the first transitionand/or the second transition may be joined at the waist elastic seam inthe front waist region and/or the back waist region. Additionally oralternatively, the first transition and/or the second transition may bejoined to the outer shell in the front waist region and/or the secondwaist region. In some embodiments, the first transition and/or thesecond transition may be integral with the chassis. In theseembodiments, the integral transition is joined with the pouch using anysuitable method, including those described herein. In some embodiments,the first transition and/or the second transition may be integral withthe shell of the chassis. For example, FIGS. 8 and 10 representativelyillustrate a transition that is integral with the shell of the chassis.In these embodiments, the integral transition is part of the shellmaterial and is a distinct projection of the shell material.

In some of the embodiments, the sling may be attached to the chassis inthe front waist region, the back waist region, and the crotch region.The sling may be attached to the chassis in the crotch region by anysuitable means. For example, the sling may be sewed, ultrasonic bonded,thermal bonded, adhesive bonded, pressure bonded, and the like, andcombinations thereof. In some embodiments, the sling may be attached tothe chassis in the crotch region via one or more tabs. The tabs may bediscrete pieces of material that are joined with both the pouch of thesling and with the chassis using any suitable means. For example, insome embodiments, the tabs may be discrete pieces of material that areultrasonically bonded to the pouch of the sling and sewn with thread tothe chassis. In various embodiments, the tabs may be attached to thechassis using any suitable sewing stitch or combinations thereof. Forexample, in some embodiments, the tabs may be attached to the chassisusing a zig zag stitch.

Referring now to FIGS. 26 and 27, the sling 152 is joined with thecrotch region 28 of the chassis 151 via discrete tabs 100 (only onevisible). Specifically, the tabs 100 are joined with the sling 152 via afirst tab seam 149. Likewise, the tabs 100 are joined with the chassis151 via a second tab seam 199. The first tab seam 149 is an ultrasonicbond to preserve the fluid-impervious pouch 206. The second tab seam 199is a thread sewn bond.

In some embodiments, the tabs may be an integral part of the sling. Forexample, the tabs may be an integral part of one or more of thecontainment flaps. In these embodiments, the sling may be joined to thechassis by joining the tabs with the chassis using any suitable means.For example, in FIGS. 11-16, the containment flap 54 includes attachmenttabs 67 extending from the proximal portion 62 of the containment flap54. As illustrated in FIGS. 15 and 16, the sling 52 is joined with thecrotch region 28 of the chassis 51 by the attachment tabs 67 (only onevisible) and tab seams 199 (only one visible).

In another example, the tab may be an integral part of the basematerial. In these embodiments, the sling may be joined to the chassisby joining the tabs with the chassis using any suitable means. In otherembodiments, the tabs may be an integral part of both the base materialand the containment flaps. For example, in FIGS. 17-22, the sidecontainment flaps 104 and 105 both include an integral attachment tab94. Likewise, the base sheet 106 includes a pair of integral attachmenttabs 96. The sling 102 may be joined with a chassis using, in part, theattachment tabs 94 and/or 96. For example, FIGS. 21 and 22representatively illustrate the sling 102 joined with the chassis 101 atthe crotch region 28 utilizing the attachment tabs 94 and 96.

In some embodiments, the slings of the present invention define aperimeter and are joined to the chassis about the perimeter.

In various embodiments, the containment flap elastic345 (not illustrated in FIG. 28) may be applied at variable tensionalong the length 347 of the flaps 330 and 332. In some embodiments, thecontainment flap elastic 345 may be applied to define a first tensionzone 380, a second tension zone 381, and a third tension zone 382. Invarious embodiments, the elastic tension in the second tension zone 381may be greater than the elastic tension in the first tension zone 380and may be greater than the elastic tension in the third tension zone382. In some embodiments, the elastic tension in the first tension zone380 may be the same as the elastic tension in the third tension zone382.

For example, in one embodiment, the containment flap relaxed length 347may be 390 mm and the containment flap elastic 345 may have a relaxedlength of 260 mm. The flap elastic 345 may be applied relaxed (i.e., noelongation) along the first 38 mm of the distal edge 343 to define thefirst tension zone 380. The elastic 345 may be applied at an elongationof 89% along the next 276 mm of the distal edge 343 to define the secondtension zone 381. In other words, 146 mm of relaxed elastic 345 isstretched to 276 mm and then applied to the distal edge 343 in thesecond tension zone 381. Finally, the elastic 345 may be applied relaxedalong the final 76 mm of the distal edge 343 to define the third tensionzone 382.

In another embodiment, the containment flap relaxed length 347 may be414 mm and the containment flap elastic 345 may have a relaxed length of273 mm. The flap elastic 345 may be applied relaxed (i.e., noelongation) along the first 38 mm of the distal edge 343 to define thefirst tension zone 380. The elastic 345 may be applied at an elongationof 85% along the next 300 mm of the distal edge 343 to define the secondtension zone 381. In other words, 162 mm of relaxed elastic 345 isstretched to 300 mm and then applied to the distal edge 343 in thesecond tension zone 381. Finally, the elastic 345 may be applied relaxedalong the final 76 mm of the distal edge 343 to define the third tensionzone 382.

In various embodiments, the containment flap elastic 345 may be appliedin the second tension zone 381 at 0 to 200% elongation, 50 to 150%elongation, or about 70 to 90% elongation. In various embodiments, thecontainment flap elastic 345 may be applied in the first tension zone380 and/or the third tension zone 382 at 0 to 150% elongation.

In various embodiments, at least one of the materials of the containmentpant is treated to be more fluid impervious. For example, in any of theembodiments described herein, at least one of the shell, waist elastic,leg elastic, transitions, base sheet, containment flaps, containmentflap elastic, and thread are treated to be more fluid impervious. Invarious embodiments, the treatment may include coating the materials inany suitable manner using a durable water resistant treatment. In someembodiments, the durable water resistant treatment may include a polymercoating. In some embodiments, the base sheet and/or the containmentflaps may include a fabric laminated with polyurethane wherein thefabric side of the base sheet is treated with a durable water resistanttreatment. In some embodiments, the base sheet and the containment flapsmay be made from a woven polyester fabric treated with a durable waterresistant treatment and laminated with a polyurethane sheet. In someembodiments, the thread used to join the containment flap elastic to thecontainment flaps may be treated with a durable water resistanttreatment.

In some embodiments, the containment pants of the present invention maybe adapted to fit a wide range of sizes. In some embodiments, anexemplary containment pant may be adapted to fit children weighingbetween 38 and 65 pounds. In some embodiments, an exemplary containmentpant may be adapted to fit children weighing between 60 and 120 pounds.To facilitate such a wide range of weight and maintain proper fit, thecontainment pants of the present invention may be adapted in the waist,hip, and/or legs to extend up to about 100% while still providingsufficient retractive force to hold the pants securely against the bodyat donning, during use, and after insult.

To measure the force-elongation profile of the containment pants, thefollowing apparatus and procedures are used. The apparatus 388 isillustrated in FIGS. 32-34 and includes a constant rate of extensiontensile tester 390. The tensile tester 390 includes a load cell 391, anupper peg 394, a lower peg 396, an upper fixture 398, and a lowerfixture 400. A test pant 392 is placed on the upper peg 394 and thelower peg 396 in various configurations. The test pant 392 is extendedin the direction 399 and the load is measured at various extensionsand/or circumferences.

In a first configuration, the test pant 392 is positioned on the upperpeg 394 and the lower peg 396 as generally illustrated in FIG. 32. Inthis configuration, the test pant 392 is positioned to measure the“whole pant waist tension”. For this test, the upper peg 394 and thelower peg 396 have a circumference of 62 mm, a length of 70 mm, and aremade from a rigid polymeric material having a smooth surface. In thisconfiguration, the upper peg 394 and the lower peg 396 are insertedthrough the waist opening 393 of the test pant 392 only to the extentnecessary to span the waist elastic 386.

In a second configuration, the test pant 392 is positioned on the upperpeg 394 and the lower peg 396 as illustrated in FIG. 33. In thisconfiguration, the test pant 392 is positioned to measure the “wholepant hip tension”. For this test, the upper peg 394 and the lower peg396 have a circumference of 78.5 mm, a length of 130 mm, and are madefrom a rigid polymeric material having a smooth surface. In thisconfiguration, the upper peg 394 and the lower peg 396 are insertedthrough the waist opening 393 of the test pant 392 and extend from theleg openings 395. The portions of the test pant 392 in contact with theupper and lower pegs 394 and 396 are centered on the respective peg.

In a third configuration, the test pant 392 is positioned on the upperpeg 394 and the lower peg 396 as illustrated in FIG. 34. In thisconfiguration, the test pant 392 is positioned to measure the “wholepant leg tension”. For this test, the upper peg 394 and the lower peg396 have a circumference of 62 mm, a length of 70 mm, and are made froma rigid polymeric material having a smooth surface. In thisconfiguration, the upper peg 394 and the lower peg 396 are insertedthrough the leg openings 395 of the test pant 392 to a depth of 1 inch.

In each of these configurations, the upper peg 394 and the lower peg 396are free to rotate about the axis 397. Before testing, the test pant 392is hung from the upper peg 394 to account for the force of the test pant392 and thus “zero” the load cell. The gauge length is selected for thewaist opening or leg opening being tested so as to provide a tension ofless than 50 grams prior to the start of the test. The upper peg 394 andthe lower peg 396 are separated until a load of 50 grams tension isattained and the gauge length is recorded and the percent elongation isdefined as zero. The upper peg 394 and the lower peg 396 are moved apartat a crosshead speed of 508 mm/min and tensions at various gauge lengthsare recorded and percent elongation is calculated. The circumference ofthe test pant 392 is calculated as two times the gauge length plus ½ thecircumference of the upper peg 394 plus ½ the circumference of the lowerpeg 396.

The tensile tester 390 may be any suitable constant rate of extensiontensile tester such as the MTS tensile tester model Synergie 200 TestBed which is available from MTS® Systems Corporation, Research TrianglePark, N.C. USA. The tensile tester includes suitable load cells selectedso the majority of the peak load values fall between the manufacturer'srecommended ranges of the load cell's full scale value.

The test procedure is conducted in standard ASTM laboratory conditions:atmosphere of 23+−2[deg.] C. (73.4+−3.6[deg.] F.) and 50+−5% relativehumidity. The test pants are measured after equilibration to laboratoryconditions.

The whole pant waist tension, whole pant hip tension, and whole pant legtension were measured for several different test pants using the testmethod described above. The results of these tests are summarized belowin Tables 7, 8, and 9. The pants included Code A, which is an exemplarypant of the present invention adapted for females in the weight range of38 to 65 pounds. Code B is an exemplary pant of the present inventionadapted for males in the weight range of 38 to 65 pounds. Code C is anexemplary pant of the present invention adapted for females in theweight range of 60 to 120 pounds. Code D is an exemplary pant of thepresent invention adapted for males in the weight range of 60 to 120pounds.

Tables 7, 8, and 9 summarize the force in grams (rounded to the nearestgram) at various circumferences as measured in mm. The percentelongation is calculated as the difference between the circumference ata given tension and the circumference at 50 grams force divided by thecircumference at 50 gram force. Each value represents the averagemeasurements of 3 pants. This data is graphically represented in FIGS.40-45.

The various containment pants of the present invention are adapted toreceive and support a discrete absorbent insert. As used herein, theterm “discrete absorbent insert” refers to a self-contained absorbentstructure that is adapted for insertion and removal from a pant withouttearing, breaking, or otherwise damaging the self-contained absorbentstructure or the pant. In some embodiments, the absorbent insert has arelatively high capacity adapted for enuretic children and/or for useovernight. In various embodiments, the pants of the present inventionare devoid of an integrated absorbent core. As used herein, the term“integrated absorbent core” refers to a mass of fibers, particulate,foam, or the like, or combinations thereof having an absorbent capacityof at least 5 g/g and being contained within a pant and not beingadapted for removal from the pant without tearing, breaking, orotherwise damaging the pant and/or the absorbent core.

Referring now to FIGS. 35 and 36, a first exemplary absorbent insert 230is representatively illustrated. FIG. 35 is a top plan view of theabsorbent insert 230 with portions cut away to better illustrateunderlying structure. FIG. 36 is an expanded cross-sectional view of theabsorbent insert of FIG. 35 taken along the line C-C. The absorbentinsert 230 defines a longitudinal-direction 48, a relatively shorter,transverse direction 50, and a thickness direction 49. The transversedirection extends generally perpendicular to the longitudinal direction,and the thickness or z-direction extends generally perpendicular to boththe longitudinal-direction and transverse direction.

The absorbent insert 230 includes a first sheet 232 and a second sheet234 in facing relation with the first sheet 232. The absorbent insert230 also includes an absorbent core 236 positioned between the firstsheet 232 and the second sheet 234. FIG. 37 is a top plan view of theabsorbent core 236 removed from the absorbent insert 230 of FIG. 35 tobetter illustrate detail. The absorbent core 236 defines a coreperimeter 238, and the first sheet 232 and the second sheet 234 extendbeyond the core perimeter 238, and are joined together to form aperimeter seal 240. The outer extent of the first sheet 232 and/or thesecond sheet 234 defines the absorbent insert perimeter 239. Theabsorbent insert perimeter 239 in turn defines an absorbent insert area269.

The absorbent insert 230 defines an absorbent insert width 266 and anabsorbent insert length 268. The absorbent insert 230 defines a firstend section 270, a second end section 272, and a central section 274 inthe longitudinal direction 48. The central section 274 extends betweenthe first end section 270 and the second end section 272. The first endsection 270 defines a first end section width 276 and a first endsection length 278. The second end section 272 defines a second endsection width 280 and a second end section length 282. The centralsection 274 defines a central section width 284 and a central sectionlength 286. The first end section length 278 plus the second end sectionlength 282 plus the central section length 286 equals the absorbentinsert length 268. The widths of the various sections are measured inthe transverse direction 50 and the lengths of the various sections aremeasured in the longitudinal direction 48.

In an embodiment adapted for use by a child weighing 60 to 120 pounds,the absorbent insert length may be 425 to 475 mm, or 430 to 450 mm, orabout 440 mm. In an embodiment adapted for use by a child weighing 38 to65 pounds, the absorbent insert length may be 375 to 425 mm, 390 to 410mm, or about 400 mm. In various embodiments, the first end sectionlength may equal the central section length which may equal the secondend section length. In other embodiments, the first end section lengthmay equal the second end section length and the central section lengthmay be different. For example, the first end section length may be about35% the absorbent insert length, the second end section length may beabout 35% the absorbent insert length, and the central section lengthmay be about 30% the absorbent insert length. In another example, thefirst end section length may be about 30% the absorbent insert length,the second end section length may be about 30% the absorbent insertlength, and the central section length may be about 40% the absorbentinsert length.

In various embodiments, the absorbent insert may have a width thatvaries at different points along the longitudinal direction. Forexample, as illustrated in FIG. 35, the absorbent insert 230 has avariable width at different points along the longitudinal direction. Inthis embodiment, the first end section 270 and the second end section272 have a maximum width that is greater than the maximum width of thecentral section 274. For example, in some embodiments, the first endsection and the second end section may have a maximum width of about 160to 210 mm, 170 to 200 mm, 180 to 190 mm or about 186 mm. In theseembodiments, the central section may have a maximum width of about 90 to130 mm, about 100 to 120 mm, or about 114 mm.

In various embodiments, the first end section, the second end section,and/or the central section may have a variable width at different pointsalong the longitudinal direction or may have a consistent width atdifferent points along the longitudinal direction. In some embodiments,the first end section and the second end section may have variable widthat different points along the longitudinal direction and the centralsection may have a consistent width at different points along thelongitudinal direction as illustrated in FIG. 35. In some embodiments,the first end section and the second end section may have a width thatvaries from 186 mm at the maximum to 114 mm at the minimum. In theseembodiments, the central section may have a consistent width of about114 mm.

In some embodiments, the absorbent insert defines a first referencewidth 316 measured at ⅛ the absorbent insert length 268, a secondreference width 317 measured at ½ the absorbent insert length 268, and athird reference width 318 measured at ⅞ the absorbent insert length 268.In some embodiments, the first reference width 316 may be equal to thethird reference width 318 and the second reference width 317 may be lessthan the first and third reference widths 316 and 318. In someembodiments, the second reference width 317 may be less than 50%, 60%,70%, or 80% the first reference width 316 and/or the third referencewidth 318. In some embodiments, the second reference width 317 may beabout 60% the first reference width 316 and the third reference width318.

The absorbent insert 230 also defines an absorbent insert area 269. Invarious embodiments, the absorbent insert area 269 may be any suitablevalue. For example, in embodiments adapted for use by a child weighing60 to 120 pounds, the absorbent insert area 269 may be about 65,000 mm².In embodiments adapted for use by a child weighing 38 to 65 pounds, theabsorbent insert area 269 may be about 57,600 mm².

In various embodiments, the absorbent insert area 269 may define anysuitable shape. For example, the absorbent insert area 269 may have asymmetric shape about the transverse centerline like that illustrated inFIG. 35 or may have an asymmetric shape about the transverse centerlinelike that illustrated in FIG. 38. In various embodiments, the absorbentinserts may have a rectangle shape, dog-bone shape, hourglass shape,T-shape, or the like.

Referring again to FIG. 37, the absorbent core 236 defines an absorbentcore width 288 and an absorbent core length 289. The absorbent core 236also defines a first end section 290, a second end section 292, and acentral section 294 in the longitudinal direction 48. The centralsection 294 extends between the first end section 290 and the second endsection 292. The first end section 290 defines a first end section width296 and a first end section length 298. The second end section 292defines a second end section width 300 and a second end section length302. The central section 294 defines a central section width 304 and acentral section length 306. The first end section length 298 plus thesecond end section length 302 plus the central section length 306 equalsthe absorbent core length 289. The widths of the various sections aremeasured in the transverse direction 50 and the lengths of the varioussections are measured in the longitudinal direction 48.

In an embodiment adapted for use by a child weighing 60 to 120 pounds,the absorbent core length may be 350 to 450 mm, 375 to 425 mm, 390 to410 mm, or about 400 mm. In an embodiment adapted for use by a childweighing 38 to 65 pounds, the absorbent core length may be 340 to 380mm, 350 to 370 mm, or about 360 mm. In various embodiments, the firstend section length may equal the central section length which may equalthe second end section length. In other embodiments, the first endsection length may equal the second end section length and the centralsection length may be different. For example, the first end sectionlength may be about 25% the absorbent core length, the second endsection length may be about 25% the absorbent core length, and thecentral section length may be about 50% the absorbent core length. Inanother example, the first end section length may be about 30% theabsorbent core length, the second end section length may be about 30%the absorbent core length, and the central section length may be about40% the absorbent core length.

In various embodiments, the absorbent core may have a width that variesat different points along the longitudinal direction. For example, asillustrated in FIG. 37, the absorbent core 236 has a variable width atdifferent points along the longitudinal direction. In this embodiment,the first end section 290 and the second end section 292 have a maximumwidth that is greater than the maximum width of the central section 294.For example, in various embodiments, the first end section and thesecond end section may have a maximum width of about 120 to 165 mm, 135to 150 mm, or about 145 mm. In some embodiments, the maximum width is atleast 120 mm, at least 130 mm, at least 140 mm, or at least 145 mm. Inthese embodiments, the central section may have a maximum width of about55 to 95 mm, 65 to 85 mm or about 75 mm. In some embodiments, thecentral section may have a maximum width of less than 110, less than100, less than 95, less than 90, less than 85, less than 80, or lessthan 75 mm.

In various embodiments, the first end section, the second end section,and/or the central section may have a variable width at different pointsalong the longitudinal direction or may have a consistent width atdifferent points along the longitudinal direction. In some embodiments,the first end section and the second end section may have variable widthat different points along the longitudinal direction and the centralsection may have a consistent width at different points along thelongitudinal direction as illustrated in FIG. 37. In some embodiments,the first end section and the second end section may have a width thatvaries from 145 mm at the maximum to 75 mm at the minimum. In theseembodiments, the central section may have a consistent width of about 75mm.

In some embodiments, the absorbent core defines a first reference width320 measured at ⅛ the absorbent core length 289, a second referencewidth 321 measured at ½ the absorbent core length 289, and a thirdreference width 322 measured at ⅞ the absorbent core length 289. In someembodiments, the first reference width 320 may be equal to the thirdreference width 322 and the second reference width 321 may be less thanthe first and third reference widths 320 and 322. In some embodiments,the second reference width 321 may be less than 40%, 50%, 60%, 70%, or80% the first reference width 320 and/or the third reference width 322.In some embodiments, the second reference width 321 may be about 50% thefirst reference width 320 and the third reference width 322.

The absorbent core also defines an absorbent core area. In variousembodiments, the absorbent core area may be any suitable value. Forexample, in an embodiment adapted for use by a child weighing 60 to 120pounds, the absorbent core area may be about 42,000 mm². In anembodiment adapted for use by a child weighing 38 to 65 pounds, theabsorbent core area may be about 36,300 mm².

In various embodiments, the absorbent core may define any suitableshape. For example, the absorbent core may have a symmetric shape aboutthe transverse centerline like that illustrated in FIG. 37 or may havean asymmetric shape about the transverse centerline like thatillustrated in FIG. 38. In various embodiments, the absorbent cores mayhave a rectangle shape, dog-bone shape, hourglass shape, T-shape, or thelike.

In various embodiments, the perimeter seal may have any suitable widthand may be formed by any suitable method. Referring again to FIGS.35-36, the perimeter seal width 241 is representatively illustrated. Insome embodiments, the perimeter seal width may be at least 5, at least10, at least 15, or at least 20 mm. The perimeter seal may includeadhesive bonding, thermal bonding, ultrasonic bonding, pressure bonding,and the like, and combinations thereof. In some embodiments, the firstsheet may be joined to the second sheet at the perimeter seal viaadhesive bonding and the perimeter seal width may be at least 20 mm. Inother embodiments, the first sheet may be joined to the second sheet atthe perimeter seal via ultrasonic bonding and the perimeter seal widthmay be at least 10 mm.

In some embodiments, the absorbent insert may be substantially devoid offluid-impervious materials. In some embodiments, the absorbent insertdoes not include a fluid-impervious barrier layer. In comparison, manyabsorbent articles include a fluid-impervious back sheet or baffle whichis provided to prevent fluid from contacting the clothes of the weareror a delay layer which is provided to slow or divert the fluid. In thepresent invention, the absorbent insert is positioned within thefluid-impervious pouch and thus does not require a fluid-imperviouslayer as part of the absorbent insert. Additionally, this design isbelieved to be beneficial in some embodiments over conventional insertsbecause fluid can be absorbed into the absorbent insert along the entirepad, including the body-facing surface, the garment-facing surface, andthe sides. Additionally, the omission of a fluid-impervious layereliminates the risk of fluid being trapped between the fluid-imperviouspouch and the absorbent insert which might cause leaking during use orleaking when removing the absorbent insert from the pouch.

In some embodiments, the absorbent insert may further include one ormore intake layers. For example, the absorbent insert 230 of FIGS. 35and 36 is illustrated with a first intake material 242 positionedbetween the first sheet 232 and the absorbent core 236. In someembodiments, the absorbent insert may additionally or alternativelyinclude a second intake material. For example, the absorbent insert 244of FIGS. 38 and 39 is illustrated with a first intake material 242 and asecond intake material 246.

Referring now to FIGS. 38 and 39, a second exemplary absorbent insert244 is representatively illustrated. FIG. 38 is a top plan view of theabsorbent insert 244 with portions cut away to better illustrateunderlying structure.

The absorbent insert 244 alsoincludes an absorbent core 248 positioned between the first sheet 232and the second sheet 234. The absorbent core 248 defines a coreperimeter 238 and the first sheet and the second sheet extend beyond thecore perimeter 238 and are joined together to form a perimeter seal 240.

The first intake material 242 is positioned between the absorbent core248 and the first sheet 232 and the second intake material 246 ispositioned between the absorbent core 248 and the second sheet 234.

In various embodiments, the first intake material and/or the secondintake material may have any suitable length, width, or shape. Forexample, referring again to FIG. 35, the first intake material 242defines an intake material width 324 and an intake material length 325.In various embodiments, the intake material width may be 50 to 70 mm orabout 62 mm. In these embodiments, the intake material width may be atleast 70%, 80%, or 90% the second reference width 317 of the absorbentcore. In some embodiments, the intake material width may be about 84%the second reference width 317 of the absorbent core.

In some embodiments, the intake material length may be about 325 to 375mm, 340 to 360 mm, or about 355 mm. In these embodiments, the intakematerial length may be at least 70%, 80%, or 90% the absorbent corelength. In some embodiments, the intake material length may be about 88%the absorbent core length.

In various embodiments, the intake materials may be rectangular asillustrated in FIG. 35 or may be any other suitable shape. For example,in various embodiments, the intake materials may be shaped similarly tothe absorbent insert and/or the absorbent core.

In various embodiments, any of the absorbent inserts of the presentinvention may include absorbent cores having absorbent material and oneor more wrap sheets. For example, in some embodiments, the absorbentcores may include a single wrap sheet folded around the longitudinalside edges of the absorbent material and overlapping upon itself to forma fully wrapped absorbent core. In other embodiments, the absorbent coremay include two wrap sheets. In these embodiments, one of the wrapsheets may be primarily positioned on a first-facing surface of theabsorbent material. The other wrap sheet may be primarily positioned onthe second-facing surface of the absorbent material. In theseembodiments, the wrap sheet on the second-facing surface may extend tothe longitudinal side edges of the absorbent material, may wrap aroundthe longitudinal side edges of the absorbent material, or may extend tothe first-facing surface of the absorbent material. Likewise, the wrapsheet on the first-facing surface may extend to the longitudinal sideedges of the absorbent material, may wrap around the longitudinal sideedges of the absorbent material, or may extend to the second-facingsurface of the absorbent material. The wrap sheets may overlapthemselves or may overlap each other.

Referring again to FIG. 36, the absorbent core 236 is representativelyillustrated with a first wrap sheet 252 positioned on a first-facingsurface 256 of the absorbent material 253. The first wrap sheet 252extends between the longitudinal side edges 260 of the absorbentmaterial 253. The absorbent core 236 also includes a second wrap sheet254 positioned on a second-facing surface 258 of the absorbent material253. The second wrap sheet 254 extends between the longitudinal sideedges 260 of the absorbent material 253.

Referring again to FIG. 39, the absorbent core 248 is representativelyillustrated with a wrap sheet 262 positioned on a first-facing surface256 of the absorbent material 253. The wrap sheet 262 extends around thelongitudinal side edges 260 of the absorbent material 253 and is alsopositioned on a second-facing surface 258 of the absorbent material 253.The wrap sheet 262 may at least partially overlay itself at overlap 264.

In various embodiments, the first sheet and the second sheet may be madeof the same material or may be different. In some embodiments, the firstsheet and the second sheet may have the same basis weight or may bedifferent. The first sheet and/or the second sheet may be fluidpermeable and may be made of substantially hydrophobic fibrous material.For example, the first sheet and/or the second sheet may be a spunbondweb composed of synthetic polymer filaments. In some embodiments, thefirst sheet and/or the second sheet may be a meltblown web or abonded-carded-web composed of synthetic polymer filaments. Suitablesynthetic polymers include, for example, polyethylene, polypropylene,polyester, and the like, and combinations thereof. In some embodiments,both the first sheet and the second sheet are spunbond polypropylenenonwoven webs having an individual basis weight of about 15 gsm. In someembodiments, the first sheet and/or the second sheet may be treated withsurfactants to adjust the degree of hydrophobicity and wettability. Insome embodiments, the first sheet and/or the second sheet may beembossed, apertured, slit, or otherwise mechanically worked.

The absorbent core typically includes absorbent material composed ofairlaid, cellulosic fibers commonly referred to as wood pulp fluff.Other natural fibers, such as cotton, may also be employed to form theabsorbent core. The absorbent core can have a density ranging from about0.18-0.30 grams/cc. This density range allows the absorbent core to besufficiently flexible to readily conform to the body of the wearer yetmaintain sufficient rigidity for insertion into the pouch. In someembodiments, the absorbent core may have a density of about 0.24grams/cc. The absorbent core may alternatively or additionally include acoform material composed of a mixture of cellulosic fibers and syntheticpolymer fibers. For example, the coform material may be composed of anairlaid blend of cellulosic fibers and meltblown polyolefin fibers, suchas polyethylene and/or polypropylene fibers. In addition, the absorbentcore may have a dry thickness of about 1 to 5 mm or about 2 mm, asmeasured under a restraining pressure of 0.068 psi (0.47 kPa).

The absorbent core may also include an effective amount of an inorganicor organic high-absorbency (e.g., superabsorbent) material to enhancethe absorptive capacity of the absorbent body. For example, theabsorbent core can contain 5-95 weight percent high-absorbency material,and preferably includes about 30-70, 40-60, or about 50 weight percentof the high-absorbency material to provide more efficient performance.In some embodiments, the absorbent core can include equal amounts offluff and superabsorbent. For example, in some embodiments, theabsorbent core may include at least 14, at least 15, at least 16, atleast 17, at least 18, or at least 19 grams of superabsorbent. In someembodiments, the absorbent core may include at least 14, at least 15, atleast 16, at least 17, at least 18, or at least 19 grams of fluff. Insome embodiments, the absorbent core may include about 19 grams ofsuperabsorbent and about 19 grams of fluff. In other embodiments, theabsorbent core may include about 17 grams of superabsorbent and about 17grams of fluff.

Suitable inorganic high-absorbency materials include, for example,absorbent clays and silica gels. Organic high-absorbency materials caninclude natural materials, such as agar, pectin, guar gum and peat moss,as well as synthetic materials, such as synthetic hydrogel polymers.Such hydrogel polymers include, for example, carboxymethylcellulose,alkali metal salts of polyacrylic acids, polyacrylamides, polyvinylethers, hydroxypropyl cellulose, polyvinyl morpholinone, polymers andcopolymers of vinyl sulfonic acid, polyacrylates, polyacrylamides,polyvinyl pyridine and the like. Other suitable polymers includehydrolyzed acrylonitrile grafted starch, acrylic acid grafted starch,and isobutylene maleic anhydride copolymers, and mixtures thereof. Thehydrogel polymers are preferably lightly cross-linked to impart desiredlevels of water insolubility to the material.

In some embodiments, the wrap sheet may be woven or non-woven materialand may be made of any suitable material. For example, the wrap sheetmay be made of polypropylene, cellulosic tissue, and the like, andcombinations thereof. In some embodiments, the wrap sheet may benonwoven material made from spunbond polypropylene and may have a basisweight of about 10 gsm.

The intake layer or layers help to decelerate and diffuse surges orgushes of fluid that can be rapidly introduced into the absorbentinsert. Desirably, the intake layer can rapidly accept and temporarilyhold the fluid prior to releasing the fluid into the absorbent core ofthe absorbent insert. In some embodiments, the intake layer may be athrough air bonded carded web composed of 40% hollow polypropylenefibers (6 denier) and 60% bicomponent fibers (6 denier) (bicomponentsheath: polypropylene core). In various embodiments, the intake layermay have any suitable basis weight. For example, the intake layer mayhave a basis weight of at least 30, at least 50, at least 75, at least100, or at least 125 grams per square meter (gsm). In some embodiments,the intake layer may have a basis weight of about 128 gsm. Otherexamples of suitable intake layers are described in U.S. Pat. No.5,486,166; U.S. Pat. No. 5,490,846; and U.S. Pat. No. 5,820,973. Theentire disclosures of these patents are hereby incorporated by referenceherein to the extent they are consistent (i.e., not in conflict)herewith.

In some embodiments, the absorbent insert may have a first intake layerand a second intake layer. In some embodiments, the first intake layermay be the same material as the second intake layer or may be different.In some embodiments, the first intake layer may have the same basisweight as the second intake layer or may be different.

In some embodiments, the absorbent inserts of the present invention maybe characterized, at least in part, by specific absorbent properties.For example, in some embodiments, the absorbent inserts may have a totalabsorbent capacity of at least 600 grams, at least 650 grams, at least700 grams, or at least 750 grams of 0.9% saline solution. In someembodiments, the absorbent inserts may have an absorbent capacity ofabout 740 grams or about 827 grams. The total absorbent capacity of theabsorbent inserts may be determined by using the Retention Capacity TestMethod. This test method measures the amount of fluid retained by anabsorbent insert under external pressure. An initial weight of theabsorbent insert is measured and then the absorbent insert is submergedin a 0.9% saline solution for 20 minutes. After the saturation time, 0.5psi pressure is applied across the entire absorbent insert for 5 minutesand the excess saline solution is allowed to drain. After the pressuretime, the weight of the saturated absorbent insert is measured. Thetotal absorbent capacity is calculated as the saturated weight minus theinitial weight.

In some embodiments, the absorbent inserts may have a first intake rateas measured through a first major surface and may have a second intakerate as measured through a second major surface which is opposite thefirst major surface. In some embodiments, the first major surface may beadapted for positioning towards the wearer's body and the second majorsurface may be adapted for positioning towards the fluid-imperviouspouch (i.e., towards the wearer's garments). In some embodiments, thefirst intake rate and/or the second intake rate may be determined by theCradle Intake Test method. This test measures the time required for anabsorbent insert to absorb a specific volume of 0.9% saline solution(insult). The absorbent insert is positioned within a pouch as describedherein and onto the test cradle with the first major surface(body-facing surface) up and the second major surface (garment-facingsurface) down toward the cradle to determine the first intake rate. Theabsorbent insert is positioned within a pouch as described herein thetest cradle with the second major surface (garment-facing surface) upand the first major surface (body facing surface) down towards thecradle to determine the second intake rate. The insult location islocated relative to the transverse center line of the pant. For productsdesigned for wearers having a weight of 38 to 65 pounds, the insultlocation is 150 mm forward of the transverse centerline for boys and theinsult volume is 120 ml. The flow rate of the saline solution is 15ml/sec and the saline has a temperature of 98.6 degrees F. Therespective absorbent inserts are insulted a first time at theaforementioned locations, volumes, and flow rates. The time it takes forthe absorbent insert to completely absorb the first insult is recorded.After 15 minutes, the respective absorbent inserts are insulted a secondtime at the aforementioned location, volumes, and flow rates. After 15more minutes, the respective absorbent inserts are insulted a third timeat the aforementioned locations, volumes, and flow rates. The time ittakes for the absorbent insert to completely absorb the second insult isrecorded.

In some embodiments, the discrete absorbent insert may have an intakerate for a first insult through the first sheet having a first value andan intake rate for a first insult through the second sheet having asecond value, wherein a difference between the first value and thesecond value is less than 20%. In other embodiments of this aspect, theabsorbent insert has an intake rate for a second insult through thefirst sheet having a first value and an intake rate for a second insultthrough the second sheet having a second value, wherein a differencebetween the first value and the second value is less than 20%. In someembodiments of this aspect, the absorbent insert has an intake rate fora third insult through the first sheet having a first value and anintake rate for a third insult through the second sheet having a secondvalue, wherein a difference between the first value and the second valueis less than 20%.

The first intake rate and second intake rate was recorded for anexemplary absorbent insert of the present invention adapted for males inthe weight range of 38 to 65 pounds using the test method describedabove. The results of these tests are summarized below in Tables 10.

TABLE 10 Intake Rate Average Average Average 1st Insult 2nd Insult 3rdInsult Intake (sec) Intake (sec) Intake (sec) First Sheet Intake Rate8.93 9.58 19.31 Second Sheet Intake Rate 9.21 10.71 21.85

Due to the design of the absorbent insert and its use within thecontainment pant, it is desirable for the first intake rate to besimilar to the second intake rate. In some embodiments, the ratio of thefirst intake rate to the second intake rate for the first insult may bebetween about 1:1.5 to about 1.5:1, or more desirably between about1:1.2 to about 1.2:1.

In some embodiments, the absorbent inserts may be characterized by totalabsorbent capacity as a ratio of crotch width. In some embodiments, theproducts designed for wearers having a weight of 60 to 120 pounds mayhave an absorbent capacity of about 827 grams and a crotch width ofabout 74 mm. In other embodiments, the products designed for wearershaving a weight of 38 to 65 pounds may have an absorbent capacity ofabout 740 grams and a crotch width of about 74 mm. Thus, in someembodiments, the ratio of total absorbent capacity to crotch width maybe at least 9 g/mm, at least 10 g/mm, or at least 11 g/mm.

The absorbent inserts of the present invention may be provided in anysuitable manner. For example, the absorbent inserts may be folded,stacked, wrapped, compressed, or the like, and combinations thereof. Insome embodiments, the absorbent inserts may be individually wrapped in awrapper. In some embodiments, the absorbent inserts may be folded one ormore times before being placed in a wrapper. In some embodiments, theabsorbent inserts may be folded twice before being placed in thewrapper.

In some embodiments, the absorbent inserts of the present inventioninclude a first sheet, a second sheet, an intake layer, and an absorbentcore. In these embodiments, the absorbent core may be positioned betweenthe first sheet and the second sheet. Additionally, the intake layer maybe positioned between the first sheet and the absorbent core. In thisconfiguration, the first sheet is designated the body side and thesecond sheet is designated as the garment side of the absorbent insert.

In various embodiments, the absorbent insert may be folded a first timesuch that a first portion of the body side is in facing relation with asecond portion of the body side. In these embodiments, the absorbentinsert may be folded a second time such that a third portion of the bodyside is in facing relation with a first portion of the garment side. Inother embodiments, the absorbent insert may be folded a first time suchthat a first portion of the garment side is in facing relation with asecond portion of the garment side. In these embodiments, the absorbentinsert may be folded a second time such that a third portion of thegarment side is in facing relation with a first portion of the bodyside.

In some embodiments, the first fold may be positioned such that theabsorbent insert is effectively folded into equal halves. In someembodiments, the first fold and the second fold may be positioned suchthat the absorbent insert is effectively folded into approximately equalthirds.

In various embodiments, the folded absorbent inserts may be individuallypackaged in any suitable wrapper material. Conventionally, the wrapperconsists of one or more layers of a thin sheet or film of thermoplasticmaterial, such as polyethylene, which is folded around the absorbentarticle and then sealed by the use of heat and/or pressure, ultrasonics,or an adhesive to form a package or pouch. In various embodiments, thewrapper may include films made from poly(vinyl alcohol), polyvinylacetate, ethylene vinyl alcohol, polyurethane, ethylene methyl acrylate,and ethylene methyl acrylic acid to make them breathable. In someembodiments, the wrapper material may also be a laminate of differentmaterials, such as a film/nonwoven laminate. The package may have asealed side or edge that is designed to be opened by breaking or tearingthe material at or adjacent the seal in order to subsequently remove theabsorbent insert. With some package designs, a flap is provided thatfolds over the pouch opening and may attach to the front of the pouchwith adhesive applied between the pouch and flap, or with a piece ofadhesive tape. The sides of the flap may be sealed with the sides of thepouch and may be separated prior to removing the absorbent article.

The containment pants and the absorbent inserts of the present inventionare adapted to work together as a containment system. In variousembodiments, the containment system includes one or more containmentpants like those described herein and one or more absorbent inserts likethose described herein. Suitable containment systems are also describedin U.S. patent application Ser. No. 13/548,012, entitled “ContainmentSystem”, filed on Jul. 12, 2012, and having attorney docket number64816460US03, the entirety of which is incorporated herein by reference.

In use and prior to donning, the absorbent inserts are positioned withinthe pouch which is suspended within the containment pant. After theabsorbent insert is positioned, the containment system is pulled intoplace like conventional underwear. The containment pant is adapted tohold the absorbent insert in position to accept one or more urineinsults from the wearer. The absorbent insert is adapted to rapidlyintake and absorb the urine. The pouch is fluid-impervious and isadapted to hold any urine that may not be immediately absorbed by theabsorbent insert. In some embodiments, the absorbent insert is fluidpermeable on the garment-facing surface and/or on the side edges as wellas the body-side surface. As such, any urine retained by thefluid-impervious pouch may be drawn into the absorbent insert via thegarment-facing surface and/or the side edges. The used absorbent insertcan be removed from the fluid-impervious pouch and the containment pantmay be laundered prior to reuse with a new absorbent insert.

In various embodiments, the absorbent inserts of the present inventionmay be secured in the pouches of the containment pants by any suitablemeans. For example, the absorbent inserts may be secured in the pouchesvia buttons, snaps, hook and loop fasteners, pressure sensitiveadhesive, clasps, and the like, and combinations thereof. In someembodiments, the absorbent inserts may be additionally or alternativelyheld in place by the structure of the containment flaps of thefluid-impervious pouch. For example, the containment flaps may includeend pockets that help secure a portion of the absorbent insert withinthe pouches. In some embodiments, the containment flaps may include flapelastic that provides retractive forces that assist in securing theabsorbent insert within the pouch. In some embodiments, the absorbentinserts are held in place only by the structure of the containment flapsand/or end pockets. In some embodiments, the absorbent inserts are heldin place only by the structure of the containment flaps and thecontainment flap elastic and are devoid of fasteners. In someembodiments, the absorbent inserts are devoid of containment flaps. Inthese embodiments, the containment of the fluid is managed by thecontainment flaps of the pouch.

In various embodiments, the containment system may include a containmentpant having a pouch with a pouch floor area, a length, width, and/orshape adapted to accommodate a specific absorbent insert having acomplementary absorbent insert and/or absorbent core area, length,width, and/or shape. This complementary area, length, width, and/orshape is believed to improve the absorbent insert placement on the body,to help contain the absorbent insert within the pouch, and to provide asmooth discrete fit and appearance for discretion.

In some embodiments, a containment pant may have a pouch with a pouchfloor having a pouch floor length. Likewise, the absorbent insert mayhave an absorbent insert length and/or an absorbent core length that isless than or equal to the pouch floor length. In some embodiments, theabsorbent insert length and/or an absorbent core length may be at least70%, at least 80%, at least 90%, or at least 95% the pouch floor length.In one embodiment, the absorbent core length may be 91% of the pouchfloor length. In these embodiments, the absorbent insert length and/oran absorbent core length may be 100% or less of the pouch floor length.Having an absorbent insert length and/or an absorbent core length topouch floor length in these ranges is believed to keep the absorbentinsert secure within the pouch without excessive bunching or shiftingthat may adversely affect performance and/or comfort. An absorbentinsert shorter than this range would be more likely to shift or breachthe pouch gasket which would likely result in leakage. An absorbentinsert longer than this range would be more likely to buckle and bunchwithin the pouch and may result in a poor user experience due todiscomfort and/or loss of discretion.

In some embodiments, a containment pant may have a pouch with a pouchfloor having a pouch floor maximum width and a pouch floor minimum widthwherein the maximum width and the minimum width are different. Likewise,the absorbent insert may have an absorbent insert and/or absorbent coremaximum width and an absorbent insert and/or absorbent core minimumwidth wherein the maximum width and the minimum width are different. Insome embodiments, the absorbent insert and/or the absorbent core maximumwidth is at least 80%, at least 90%, or at least 95% the pouch floormaximum width. In one embodiment, the absorbent core maximum width is85% of the pouch floor maximum width. In these embodiments, theabsorbent insert and/or absorbent core maximum width may be 100% or lessof the pouch floor maximum width. In some embodiments, the absorbentinsert and/or the absorbent core minimum width is at least 80%, at least90%, or at least 95% the pouch floor minimum width. In one embodiment,the absorbent core minimum width may be 91% of the pouch floor minimumwidth. In these embodiments, the absorbent insert and/or the absorbentcore minimum width may be 100% or less of the pouch floor minimum width.

In some embodiments, a containment pant may have a pouch with a pouchfloor having a pouch floor maximum width in a front portion and/or aback portion and a pouch floor minimum width at a central portionwherein the maximum width and the minimum width are different. Likewise,the absorbent insert and/or absorbent core may have an absorbent insertand/or absorbent core maximum width in a front portion and/or a backportion and an absorbent insert and/or absorbent core minimum width at acentral portion wherein the maximum width and the minimum width aredifferent. In some embodiments, the minimum width of the pouch floor maybe less than 80%, less than 70%, less than 60%, or about 62% the maximumwidth of the pouch floor. Similarly, the minimum width of the absorbentinsert and/or absorbent core may be less than 80%, less than 70%, lessthan 60%, or about 62% the maximum width of the absorbent insert and/orabsorbent core.

However, despite the differences between the first containment pant andthe second containment pant, both may be constructed with pouches havingpouch floors having similar length, width, and/or shape. As such, asingle absorbent insert may be provided for use with both the firstcontainment pant and the second containment pant. For example, in someembodiments, the present invention provides a method for providing acontainment system. The method includes providing a first permanentlyclosed containment pant like those described herein and providing asecond permanently closed containment pant like those described herein.The method also includes providing a discrete absorbent insert that issized and shaped to work in conjunction with both the first containmentpant and the second containment pant. In some embodiments, the firstcontainment pant may include a first pouch and the second containmentpant may include a second pouch having a similar size and shape to thefirst pouch. However, despite the similarities, the first containmentpant and the second containment pant may have different chassisconstruction, pouch construction, sling construction, pouch placement,or other differences, or combinations thereof.

In some embodiments, the containment system of the present inventionincludes one or more absorbent inserts having a designated body side anda designated garment side. In other words, in some embodiments, theabsorbent inserts are designed to be oriented with a particular sidetowards the user to maximize the performance of the absorbent insert.For example, in some embodiments, the absorbent insert may have a singleintake layer located on one side of the absorbent core. In theseembodiments, it is desirable for the user to orient the absorbent insertwithin the pouch such that the intake layer faces the user. In thisorientation, the absorbent insert is positioned to intake fluid rapidlythrough the intake layer and retain the fluid in the absorbent core.

To assist users in properly orienting the absorbent insert in the pouch,various cues may be provided. In some embodiments, the absorbent insertmay include a color on one or more of the components. In someembodiments, the absorbent insert may include an intake layer that has acolor that is distinguishable from the other components of the absorbentinsert. For example, in some embodiments, the intake layer may have ablue color and the surrounding components may have a white color. Inthese embodiments, the user may be directed to identify the blue intakelayer and position it facing the body. In this way, the user has asimple visual cue to quickly, repeatably, and properly orient theabsorbent insert within the pouch.

In some embodiments, the absorbent inserts may be provided folded inindividual wrappers. In these embodiments, the absorbent inserts may befolded to define a direction of curvature. The absorbent inserts may bebi-folded, tri-folded, or the like. In these embodiments, the absorbentinserts may be folded such that the resulting curvature is directed tothe side of the absorbent insert that is desirably oriented towards thewearer. For example, the absorbent insert may have a single intake layerlocated on one side of the absorbent core. The absorbent insert may befolded such that the absorbent insert is cupped towards the side havingthe intake layer. In use, this cupped formation naturally fits with thecupped formation of the pouches within the containment pants. As such,the user is cued to position the absorbent insert within the pouch withthe intake layer oriented towards the body of the wearer.
